who is the point-tuza croaker
The brown croaker is a bottom-dwelling fish of the family Sciaenidae, living in shallow waters of the eastern Pacific, from the Gulf of California to Peru. It grows to 35 cm, with a common size of 25 cm. It feeds mainly on shrimp and other invertebrates that live on the bottom. It is frequently found in local markets and appears as a catch in small-scale commercial fishing. It has a dorsal fin divided into two parts, like croakers in general.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the point-tuza croaker; in the meantime, see the similar species.
identification
Elongated body of a croaker, with the dorsal fin divided into two parts. The name parda (brown) suggests a dark, brownish colour on the body. It lives on the bottom, in shallow water. On the same coast, the bigeye croaker (Corvula macrops) is a small croaker of rocky areas, up to 25 cm, while the brown croaker reaches 35 cm and lives on the bottom in shallow waters.
